One of the major constraints of wireless sensor networks is limited energy available to sensor nodes because of the small size of the batteries they use as source of power. Clustering is one of the routing techniques that ...

Young women's sexuality is a contested terrain in multiple ways in contemporary
South Africa. A growing body of work in the context of HIV and gender-based
violence illustrates how young women find it challenging to ...

Gender-based violence is a problem in most Southern African countries and yet it has generally received little attention from governments and civil society—including Christian churches. In recent years, some churches have ...

The structural growth and optical and photovoltaic properties of the organic–inorganic hybrid
structures of zinc
oxide (ZnO)-nanorods/poly-3-hexylthiophene (P3HT) and two variations of organic polymer blends of
ZnO/ ...

We have applied bioluminescent ATP detection
methods to microbial enumeration in Antarctic Dry Valley
mineral soils, and validated our ATP data by two independent
methods. We have demonstrated that ATP measurement
is ...

This article seeks to address a fundamental shift that has occurred in reality; a displacement that requires us to critically account for the ways in which knowledge is both being produced and taught at universities. The ...

Due to the rise inmulti-drug resistant pathogens and other diseases, there is renewed interest
in marine sponge endosymbionts as a rich source of natural products (NPs). The South African marine
environment is rich in ...

Background: Antibiotic resistance is a significant public health problem. Prudent use of antibiotics is crucial in reducing this resistance. Acute bronchitis is a common reason for consultations with general medical ...

Phytochemical studies on Rhus natalensis root bark collected from Kenya led to the isolation and
identification of a new biflavonoid (3-(1-(2,4-dihydroxyphenyl)-3,3-bis(4-hydroxyphenyl)-1-oxopropan-2-
yl)-7-methoxy-4H-ch ...

Background: Honey has been shown to have wound healing properties which can be ascribed to
its antimicrobial activity. The antimicrobial activity can be effective against a broad spectrum of
bacterial species especially ...

The vaginal microbiota of a healthy asymptomatic woman consists of an extensive diversity of anaerobic and aerobic bacterial genera and species dominated by the microaerophilic genus Lactobacillus , known to inhibit the ...

Sub-therapeutic doses of antimicrobial agents are administered
routinely to poultry to aid growth and to prevent disease, with prolonged exposure
often resulting in bacterial resistance. Crossover of antibiotic resistant ...

Could we think of the black subject under apartheid as a refugee, and might this
condition be the paradigmatic metaphor for thinking about the postcolonial African
predicament of citizenship? This paper considers the ...

This paper sets to work on strategies for forging new and critical humanities at the institutional site of the university that appears to be trapped in the legacies of apartheid. The paper suggests that the university's ...

Laser is the acronym for Light Amplification by Stimulated
Emission of Radiation, a usage that dates back to
approximately 50 years ago. In 1960, the first functioning
laser was built by the American physicist Maiman ...

This article describes how the cognitive transactional model of stress-appraisal-coping can be applied in the sense making process for students working in the challenging mental health care environment. Primary and secondary ...

Recharge estimation in arid and semi-arid areas is very challenging. The chloride mass balance method applied in western
South Africa fails to provide reliable recharge estimates near coastal areas. A relationship between ...

In this paper, we report a new concept to construct a label-free electrochemical
inhibition-based immunosensor for the detection of the mycotoxin deoxynivalenol (DON)
in cereal samples. The electrochemical impedance ...

Background: Mobile phone technology has demonstrated the potential to improve health service delivery, but
there is little guidance to inform decisions about acquiring and implementing mHealth technology at scale in
health ...

This paper examines the effectiveness of linguistic analysis in developing scientific thinking
skills and scientific attitudes. It reports on a project established at a South Africa university
in South Africa which engaged ...
